Spare Time Gizmo’s ELF2K running Mike Riley’s ELFOS

http://cottageworker.com/wp-content/uploads/2014/05/

The mess on the left is a breadboarded MAX232 RS232 interface wired into the DS275 socket (Still waiting for that chip to arrive)

I didn’t have the guts to solder in the CF card connector, I went with the IDE interface (for now 🙂 )
